Specification of Letters Patent.

Original application filed December 5, 1911, Serial N0.-664,126. Divided and this application filed August Serial No. 786,584.

Z '0 all whom it may concern:

Be it known that I, JOSEPH V. WEGK- BAUGH, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented a new and useful Method for Inserting Rivets in Reblade- Knives; and I do declare the following to be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a method for inserting rivets in re-blade knives, or knives so constructed that. the blades are readily removable.

This invention is a division of my former application, Serial No. 664,126, filed December 5, 1911, and is particularly intended for inserting the female member of a rivet composed of male and female parts interlocked by a screw thread.

The method consists in applying the female member of the rivet to the reduced extremity of the tool which is pointed at one end, inserting the pointed end of thetool first through the rivet holes of the blade and handle of the knife until the female member of the rivet takes its proper position, then removing the tool and insertmg the male member of the rivet, which has a threaded portion which isthe counterpart of the threaded socket in the female member.

2 Before entering into a more detailed description of the method, I will first describe a suitable mechanical construction for carrying out or practising the inventlon.

In the accompanying drawmg, forming a part of this specification I have illustrated I a suitable device which ma be employed in practising this method, t is device being also illustrated in connection with the han-' dle, blade and main spring of a knife of the construction to which the mventlon s applicable. V I 4 In this'drawing, Flgure 1 1s a detail view of a tool adapted for use in this connection showing the same before it has been connected with the femalemember o r tubular part of the-rivet. Fig. 2 is a det a1l view of the female rivet member. Fig. 3 1s a similar view of the male member. Fig. 4 a view sectional view similar to Fig. 7,

rearwarclly to cause the perforation in the tang of the blade to'register with theperforation of'the handle members. Fig. 6 is a. view illustrating the manner of usin the needle in connection with the handle and blade of the knife, the last named parts being shownin section, taken on the line 66, Fig. '5, but shown on a larger scale. Fig. 7 is a similar view showing the needle at its limit of movement, the female member of the rivet being in place. Fig. 8 is a showing the two rivet members connected.

In this drawing, the same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the needle whose cylindrical body portion 6 is equal in diameter to the rivet to be used in connecting a blade 7 with a handle 8. One extrepnity of this needle is cone-shaped as shown at 9 whil its opposite extremity'is reduced and preferably plain or unthreaded as shown at 10, and of such size that it readily enters the threaded'socket of the rivet without interfering with or injuring Hence, this form of construction is illustrated in the drawing. As just intimated, this part 10 is adapted to enter the threaded socket formed in a female rivet member 12, whose head is upset and providedwith a nick, making it practicable to use a screw driver in connecting the same with the male member 13 of the rivet.

Preparatory to beginning the process or method covered in this application, the tang of the blade 7 is passed into the extremity of the handle with which it is to be connected, as far as the main spring Wi ermit without forcing the latter rearwar y. Under these circumstances, there is a small art 14 of the perforation in the tang 15 o the blade which overlaps or registers with a perforation 16 in the handle extremity. As soon as this is done, and the female member of the rivet is applied to the extremlty 10 of the needle,- the cone-shaped extremity 9 of the latter, is insertedin the reglstering portions of the perforation '16 and 17 in the blade and handle, respectively, and the needie is forced forwardly to cause its body portion 6 to enter the perforations of the blade and handle, and as the part 6 of the needle is of the same size as the female member 12 of the rivet, this member is readily inserted in the said perforations. The needle 5 is then disconnected from the female member of the rivet and the male member of the latter which isalso provided with a screw head is inserted there n.

Having thus described my invention, what I claim is:

I. A method for inserting rivets in re-'- blade pocket knives, where in the absence of Z a rivet, the spring of the handle tends to force the rivet hole of the bladeout of line with the holes of the handle, consisting in applying the female member of the rivet to the reduced extremity ofa tool, inserting the tool, inserting the tool through the rivet holes in the blade and handle of the knife until the said rivet'member takes its proper position, and then removing the'tool- In testimony whereof I aflix my signature in presence of two witnesses.
